The updates were smooth and I think I'll like the new LR. Two things jump out. The addition of the Haze filter to the Basic panel is a nice positive. The new Profile section in the Basic panel is interesting. It's essentially like a bunch of preset options - and you can view thumbs for each one. My guess is I'll quickly narrow to a few favorites. But these profiles are not adjustable using sliders the way presets are - its a different way of rendering a file starting point. I saw very little difference between Adobe Standard and Camera Standard. If you want something completely different, there are some interesting artistic options.

I reading conflicting information how to create your own looks. Basically its a LUT, look up table, that can affect colors. Sort of like color grading. In PS, you can create your own LUTs. It would be nice to create your own.

Just to clarify, the Creative Profiles have an opacity slider that pops up after you select the profile. The standard profiles in the top group - Adobe and Camera Profiles - do not have an opacity slider.

One of the interesting things about the Profiles is that Adobe has opened them up to developers - kind of like actions or plug-ins - and we'll see a lot of profiles available for sale in the future. I expect some of the more active educators will be selling packs of presets and profiles.
